Description

Technical Field

[0001] The invention relates to the technical field of artificial leather processing and conveying equipment, in particular to artificial leather processing and conveying equipment capable of preventing scratches. Background Art

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of leather. It is usually made of fabric as the base, coated with synthetic resin and various plastic additives. There are three main types: PVC artificial leather, PU artificial leather and PU synthetic leather. Artificial leather is a material widely used in the production of bags, clothing, shoes, vehicles and furniture decoration. Its characteristics include soft and natural luster, soft feel, excellent adhesion to the substrate, wear resistance, flex resistance, aging resistance and other excellent mechanical properties. In addition, artificial leather also has the advantages of good cold resistance, breathability, washability, easy processing, and low price. Therefore, it is considered to be an ideal substitute for natural leather. The wide range of applications, large quantity and variety of artificial leather are beyond the reach of traditional natural leather.

[0003] In the process of transporting artificial leather by existing equipment, the artificial leather itself is prone to deflection, so that the artificial leather is not transported according to the original track. Once the deflection cannot be corrected in time, it will not only affect the subsequent normal work of the artificial leather, but also often require special staff to pull the deflected artificial leather when deflection occurs. However, manual pulling requires continuous operation, which is time-consuming and labor-intensive, and the manual pulling error is large. Summary of the invention

[0004] To achieve the above purpose, the present invention is implemented by the following technical solutions: an artificial leather processing and conveying device for preventing scratches, comprising a frame, a motor is fixedly connected to the outer side of the frame, and the output end of the motor passes through the frame and extends to the inside; A rotating assembly is rotatably connected to the frame, the rotating assembly is fixedly connected to the output end of the motor, an outer wall of the rotating assembly close to the frame is rotatably connected to a transmission belt, there are multiple rotating assemblies, and the multiple rotating assemblies are connected through the transmission belt; The limiting assembly is fixedly installed at the middle of the top of the frame, and the limiting assembly and the rotating assembly are arranged alternately; The rotating assembly comprises a rotating shaft, which is fixedly connected to the output end of the motor, a circular plate is fixedly connected to the outer side of the rotating shaft, a round rod is fixedly connected to the outer side of the circular plate, the circular plate is symmetrically arranged on the rotating shaft with the round rod as the center, a positioning plate is fixedly connected to the middle of the outer side of the rotating shaft, and a spring is fixedly connected to the outer side of the positioning plate. In the initial state, under the elastic force of the spring, the cylinders on both sides are tightly fitted to the middle, so that the limiting ring and the middle ring located in the middle of the cylinder are in contact, and the artificial leather is placed on the cylinder, and the artificial leather is conveyed on the negative pressure adsorption cylinder. Since the contact of the cylinder surface is softer, the damage to the artificial leather surface caused by friction is reduced. When the material is offset, the cylinder on the offset side is forced to move in the direction away from the positioning plate. At this time, extrusion is generated between the limiting ring and the middle ring, and then the limiting ring and the middle ring move relatively, so that the artificial leather is balanced under the friction between the cylinder on the non-offset side and the artificial leather, and then the elastic force of the spring Under the action, the cylinder is reset. At this time, the artificial leather moves toward the cylinder on the non-deviated side under the push of the cylinder on the offset side, so that the middle part of the artificial leather is located in the middle part of the two cylinders. When the artificial leather is supported by the cylinder in the middle position, it is more balanced, which can effectively prevent the local area from being deformed due to excessive force. At the same time, it is helpful for accurate positioning, reduces the processing error caused by position deviation, and improves the processing accuracy and quality consistency of the product. A sliding groove is provided on the outer side of the rotating shaft, and a slider is slidably connected to the outer side of the sliding groove. Through the sliding cooperation between the sliding groove and the slider, it plays a guiding role. The end of the spring away from the positioning plate is fixedly connected to the slider, and the outer side of the slider is fixedly connected to the cylinder, and the end of the cylinder close to the positioning plate is fixedly connected to the limiting ring. The end of the limiting ring away from the cylinder is slidably connected to the intermediate ring, and the contact surface between the intermediate ring and the limiting ring is inclined.

A circular hole is opened on the outer side of the cylinder. During the transportation of the material, cold air is introduced into the inside of the cylinder. The air passes through the inside of the cylinder, so that negative pressure is generated at the circular hole. At this time, the material located above the cylinder is adsorbed. The negative pressure adsorption can generate strong suction force, so that the artificial leather fits tightly to the surface of the drum, effectively preventing the artificial leather from being displaced due to external force. At the same time, the uniform adsorption force can keep the artificial leather flat and avoid wrinkles or curling, and the cylinders on both sides are symmetrically arranged The spirally arranged circular holes provide an axial outward force to the two edges of the artificial leather, so that the artificial leather can be unfolded to avoid wrinkles. There are multiple circular holes, which are spirally arranged with the rotating shaft as the center. There are two springs, which are symmetrically arranged with the positioning plate as the center. A guide groove is provided on the inner wall of the cylinder. By providing the guide groove, cold air can flow through the circular holes along the spiral plate to prevent impurities adsorbed near the circular holes from accumulating around the circular holes. The guide groove and the circular holes are located on the same spiral line. A groove is provided on the outer side of the slider. The cylinder is fixedly connected with a fixing plate near the groove. The cylinder and the slider are snap-fitted between the fixing plate and the groove.

[0006] Preferably, the connecting member includes a rotating plate, which is fixedly connected to the end of the rotating shaft, and a slot is provided on the outer side of the rotating plate. There are multiple slots, and the multiple slots are evenly distributed around the rotating shaft. A fixed frame is arranged inside the slot, and the fixed frame is elastic. When the motor is connected to an external power supply, the motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to rotate. During the rotation of the rotating plate, a protrusion on the transmission belt enters the interior of the slot, and the protrusion contacts and squeezes the limit block, so that the fixed frame is deformed by force, so that the opening of the fixed frame moves toward the direction of the protrusion, and the open end of the fixed frame contacts the protrusion, and the rotating plate drives the transmission belt to rotate, so that multiple rotating components rotate synchronously. By setting the fixed frame and the protrusion to engage with each other, the meshing transmission method effectively avoids slipping between the transmission belt and the rotating component. At the same time, when the load changes, the meshing structure can ensure the synchronous movement between the transmission belt and the rotating component, and the fixed frame is set to an open hexagon, and the middle part of the inner wall of the fixed frame is fixedly connected to the limit block, and the limit block is symmetrically arranged in the middle of the interior of the fixed frame.

[0008] The buffer assembly includes a fixed cylinder, which is fixedly installed on the top of the supporting plate. An arc groove is provided on one side of the fixed cylinder close to the cylinder. A brush is provided on the inner wall of the arc groove. The brush is located on the side away from the motor. A square hole is provided on the inner wall of the arc groove away from the brush. When the artificial leather is placed on the conveying equipment, the artificial leather contacts the top of the roller. Under the action of the artificial leather's own gravity, the roller is forced to drive the contact block to move downward through the connecting rod, so that the contact block slides downward inside the inner semicircular groove of the U-shaped plate. At the same time, the U-shaped plate is subjected to the action of the extrusion force, and the opening of the U-shaped plate is deformed and extended outward. A buffering effect is played by setting the U-shaped plate. After the artificial leather is placed, the motor is connected to the external power supply to work, the motor drives the rotating shaft to rotate, and the rotating shaft drives the cylinder to rotate. At this time, the cylinder rotates and contacts with the brush, and the brush contacts the cylinder. The surface of the cylinder is cleaned, and when the weight of the artificial leather cannot make the roller flush with the top of the cylinder, the cylinder contacts the limit rod when it rotates, and the friction between the cylinder and the limit rod is used to drive the connecting rod to move downward, and the spring plate is deformed until the top is flush, and the limit rod is located inside the square hole and does not contact the cylinder, a U-shaped plate is provided inside the fixed cylinder, a semicircular groove is provided inside the U-shaped plate, and a contact block is slidably connected to the inside of the semicircular groove, a through groove is provided on the outside of the fixed cylinder, and the through groove and the arc groove are alternately arranged, a square rod is fixedly connected to the outside of the contact block, and the square rod is located inside the through groove, a connecting rod is fixedly connected to the top of the contact block, and a spring plate is fixedly connected to the outside of the connecting rod, and an end of the spring plate away from the connecting rod is fixedly connected to the limit rod, and the limit rod is located inside the square hole.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0016] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: an artificial leather processing and conveying device for preventing scratches, comprising a frame 1, a motor 2 is fixedly connected to the outer side of the frame 1, and an output end of the motor 2 passes through the frame 1 and extends to the inside; A rotating assembly 3, the rotating assembly 3 is rotatably connected to the frame 1, the rotating assembly 3 is fixedly connected to the output end of the motor 2, the outer wall of the rotating assembly 3 close to the frame 1 is rotatably connected with a transmission belt 5, there are multiple rotating assemblies 3, and the multiple rotating assemblies 3 are connected through the transmission belt 5; The limiting assembly 4 is fixedly installed at the middle of the top of the frame 1, and the limiting assembly 4 and the rotating assembly 3 are arranged alternately; The rotating assembly 3 includes a rotating shaft 31, which is fixedly connected to the output end of the motor 2. A circular plate 33 is fixedly connected to the outer side of the rotating shaft 31, and a round rod 34 is fixedly connected to the outer side of the circular plate 33. The circular plate 33 is symmetrically arranged on the rotating shaft 31 with the round rod 34 as the center. A positioning plate 315 is fixedly connected to the middle of the outer side of the rotating shaft 31, and a spring 314 is fixedly connected to the outer side of the positioning plate 315. In the initial state, under the elastic force of the spring 314, the cylinders 35 on both sides are tightly fitted to the middle, so that the limiting ring 310 and the middle ring 36 located in the middle of the cylinder 35 are in contact, The artificial leather is placed on the cylinder 35, and the artificial leather is transported on the negative pressure adsorption cylinder 35. Since the contact with the surface of the cylinder 35 is softer, the damage to the surface of the artificial leather caused by friction is reduced. When the material is offset, the cylinder 35 on the offset side is forced to move in the direction away from the positioning plate 315. At this time, the limiting ring 310 and the middle ring 36 are squeezed, and then the limiting ring 310 and the middle ring 36 move relative to each other, so that the friction between the cylinder 35 on the non-offset side and the artificial leather causes the force to be balanced, and then the elastic force of the spring 314 acts Under the action of the cylinder 35, the cylinder 35 is reset. At this time, the artificial leather moves toward the cylinder 35 on the non-deviated side under the push of the cylinder 35 on the offset side, so that the middle part of the artificial leather is located in the middle of the two cylinders 35. When the artificial leather is supported by the cylinder 35 in the middle position, it is more balanced, which can effectively prevent the local area from being deformed due to excessive force, and at the same time, it is helpful for accurate positioning, reducing the processing error caused by position deviation, and improving the processing accuracy and quality consistency of the product. A slide groove 313 is provided on the outer side of the rotating shaft 31, and a slider 316 is slidably connected to the outer side of the slide groove 313. The sliding fit between the slide groove 313 and the slider 316 plays a guiding role. The end of the spring 314 away from the positioning plate 315 is fixedly connected to the slider 316. The outer side of the slider 316 is fixedly connected with a cylinder 35. The end of the cylinder 35 close to the positioning plate 315 is fixedly connected with a limiting ring 310. The end of the limiting ring 310 away from the cylinder 35 is slidably connected with an intermediate ring 36. The contact surface between the intermediate ring 36 and the limiting ring 310 is inclined. The outer side of the round rod 34 is fixedly connected with a fixing ring 311, and the fixing ring 311 is located in the middle of the limiting ring 310 and the round rod 34.

[0017] The second embodiment is based on the first embodiment. Figures 3 to 6As shown, the transmission belt 5 is provided with a convex block near the inner part of the rotating component 3, and there are multiple round rods 34, which are evenly distributed around the rotating shaft 31. The end of the rotating shaft 31 is fixedly connected with a connecting piece 32, and the connecting piece 32 is rotatably connected to the transmission belt 5. A circular hole 37 is opened on the outer side of the cylinder 35. During the transportation of the material, cold air is introduced into the inside of the cylinder 35. The air passes through the inside of the cylinder 35, so that negative pressure is generated at the circular hole 37. At this time, the material located above the cylinder 35 is adsorbed. The negative pressure adsorption can generate a strong suction force, so that the artificial leather fits tightly to the surface of the drum, and effectively prevents the artificial leather from being displaced due to external force. At the same time, the uniform adsorption force can keep the artificial leather flat and avoid wrinkles or curling. The spirally arranged circular holes 37 symmetrically arranged on the cylinders 35 on both sides can be used to absorb the two edges of the artificial leather. An axial outward force is provided to unfold the artificial leather and avoid wrinkles. There are multiple circular holes 37, which are spirally arranged with the rotating shaft 31 as the center. There are two springs 314, which are symmetrically arranged with the positioning plate 315 as the center. A guide groove 312 is provided on the inner wall of the cylinder 35. By providing the guide groove 312, cold air flows through the circular hole 37 along the spiral plate 39 to prevent impurities adsorbed near the circular hole 37 from accumulating around the circular hole 37. The guide groove 312 and the circular hole 37 are located on the same spiral line. A groove 317 is provided on the outer side of the slider 316. The cylinder 35 is fixedly connected to a fixing plate 38 near the groove 317. The cylinder 35 and the slider 316 are snap-fitted between the fixing plate 38 and the groove 317. The cylinder 35 is fixedly connected to a spiral plate 39 near the inner wall of the guide groove 312.

[0018] The third embodiment is based on the first and second embodiments. Figure 7As shown, the connecting member 32 includes a rotating plate 321, and the rotating plate 321 is fixedly connected to the end of the rotating shaft 31. A slot 324 is provided on the outer side of the rotating plate 321. There are multiple slots 324, and the multiple slots 324 are evenly distributed around the rotating shaft 31. A fixed frame 322 is provided inside the slot 324. The fixed frame 322 is elastic. When the motor 2 is connected to an external power supply and works, the motor 2 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the rotating plate 321 to rotate. During the rotation of the rotating plate 321, the protrusion on the transmission belt 5 enters the interior of the slot 324, and the protrusion contacts and squeezes the limit block 323, so that the fixed frame 322 is deformed by force, thereby making the opening of the fixed frame 322 The rotating plate 321 drives the transmission belt 5 to rotate, thereby the multiple rotating components 3 rotate synchronously. By setting the fixed frame 322 and the protrusion to engage with each other, the meshing transmission method effectively avoids slipping between the transmission belt 5 and the rotating component 3. At the same time, when the load changes, the meshing structure can ensure the synchronous movement between the transmission belt 5 and the rotating component 3. The fixed frame 322 is set to an open hexagon. The middle part of the inner wall of the fixed frame 322 is fixedly connected to the limit block 323. The limit block 323 is symmetrically arranged in the middle of the inner part of the fixed frame 322. The transmission belt 5 and the rotating plate 321 are rotatably connected through the protrusion and the slot 324.

[0019] For the fourth embodiment, please refer to Figures 8 to 9 As shown, the limiting component 4 includes a support plate 41, which is fixedly mounted on the frame 1, and the support plate 41 is located in the middle of the two rotating components 3. A buffer component 42 is fixedly connected to the top of the support plate 41. There are multiple buffer components 42, and the multiple buffer components 42 are evenly arranged on the top of the support plate 41. A connecting frame 43 is fixedly connected to the top of the buffer component 42, and a roller 44 is rotatably connected to the inner wall of the connecting frame 43.

[0020] The buffer assembly 42 includes a fixed cylinder 421, which is fixedly mounted on the top of the support plate 41. An arc groove 422 is provided on the side of the fixed cylinder 421 close to the cylinder 35. A brush 423 is provided on the inner wall of the arc groove 422. The brush 423 is located on the side away from the motor 2. A square hole 4211 is provided on the inner wall of the arc groove 422 away from the brush 423. When the artificial leather is placed on the conveying device, the artificial leather contacts the top of the roller 44. Under the action of the gravity of the artificial leather itself, the roller 44 is driven by the connecting rod 426. The contact block 427 moves downward, so that the contact block 427 slides downward inside the inner semicircular groove 428 of the U-shaped plate 424. At the same time, the U-shaped plate 424 is deformed and extended outward at the opening under the action of the extrusion force. By setting the U-shaped plate 424, a buffering effect is played. After the artificial leather is placed, the motor 2 is connected to the external power supply to work, the motor 2 drives the shaft 31 to rotate, and the shaft 31 drives the cylinder 35 to rotate. At this time, the cylinder 35 rotates and contacts with the brush 423, and the brush 423 cleans the surface of the cylinder 35. When the artificial leather is heavy, When the roller 44 is not flush with the top of the cylinder 35, the cylinder 35 contacts the limiting rod 4210 when rotating. The limiting rod 4210 drives the connecting rod 426 to move downward by utilizing the friction between the cylinder 35 and the limiting rod 4210. At the same time, the spring plate 429 is deformed until the top is flush. The limiting rod 4210 is located inside the square hole 4211 and does not contact the cylinder 35. The interior of the fixed cylinder 421 is provided with a U-shaped plate 424. The interior of the U-shaped plate 424 is provided with a semicircular groove 428. The inner part of the semicircular groove 428 A contact block 427 is slidably connected to the fixed cylinder 421, a through groove 4212 is provided on the outer side of the fixed cylinder 421, and the through groove 4212 and the arc groove 422 are alternately arranged. A square rod 425 is fixedly connected to the outer side of the contact block 427, and the square rod 425 is located inside the through groove 4212. A connecting rod 426 is fixedly connected to the top of the contact block 427, and a spring plate 429 is fixedly connected to the outer side of the connecting rod 426. The end of the spring plate 429 away from the connecting rod 426 is fixedly connected to a limiting rod 4210, and the limiting rod 4210 is located inside the square hole 4211.

[0021] When in use, when the artificial leather is placed on the conveying device, the artificial leather contacts the top of the roller 44. Under the action of the artificial leather's own gravity, the roller 44 is forced to drive the contact block 427 to move downward through the connecting rod 426, so that the contact block 427 slides downward inside the inner semicircular groove 428 of the U-shaped plate 424. At the same time, under the action of the squeezing force, the opening of the U-shaped plate 424 is deformed and extended outward. The U-shaped plate 424 plays a buffering role. After the artificial leather is placed, the motor 2 is connected to the external power supply to work, and the motor 2 drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the cylinder 35 to rotate. At this time, the cylinder 35 rotates and contacts the brush 423. The brush 423 cleans the surface of the cylinder 35. When the weight of the artificial leather cannot make the roller 44 flush with the top of the cylinder 35, the cylinder 35 rotates and contacts the limiting rod 4210. Using the friction between the cylinder 35 and the limiting rod 4210, the limiting rod 4210 drives the connecting rod 426 to move downward. At the same time, the spring plate 429 is deformed until the top is flush. The limiting rod 4210 is located inside the square hole 4211 and does not contact the cylinder 35.

[0022] The motor 2 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the rotating plate 321 to rotate. During the rotation of the rotating plate 321, the protrusion on the transmission belt 5 enters the interior of the card slot 324, and the protrusion contacts and squeezes the limit block 323, so that the fixed frame 322 is deformed by force, so that the opening of the fixed frame 322 moves toward the direction of the protrusion, and the open end of the fixed frame 322 contacts the protrusion, and the rotating plate 321 drives the transmission belt 5 to rotate, so that the multiple rotating components 3 rotate synchronously, and then the artificial leather is transported.

[0023] When the material is offset, the cylinder 35 on the offset side is forced to move in the direction away from the positioning plate 315. At this time, extrusion is generated between the limit ring 310 and the middle ring 36. Then the limit ring 310 and the middle ring 36 move relative to each other, so that the friction between the cylinder 35 on the non-offset side and the artificial leather causes force balance. Then, under the elastic force of the spring 314, the cylinder 35 is reset. At this time, the artificial leather is pushed by the cylinder 35 on the offset side and moves toward the cylinder 35 on the non-offset side, so that the middle part of the artificial leather is located in the middle of the two cylinders 35.

[0024] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
